2 Claims.

the invention will be which Figure 1 is a side elevation of one form ofthe improvement in position Figure 2 is a top plan on the spindle. Viewof the same.

Figure 3 is a side elevation of an equalizer mounted on a fiyer abovethe fiyer wires.

Figure 4 is a perspective view of the same.

Figure 5 is a sectional used on equalizer arm device.

View of adjustable weight showing spring fastening Referring to Figure 1of the drawing, 1 indicates a spindle of a bobbin mounted there theusual tapered form, and 2 on. 3 indicates a wooden fiyer block on thespindle 1 adjacent to the top of the bobbin 2 and prevented fromchanging its level by the mill nut 4, which may be held securely in anyand all wires of a four arm positions. flyer secured to the fiyer block3 by any suitable means.

5 indicates the The adjacent unthreaded arms of the fiyer wires are heldtogether by a counterbalancing weight 6. a

Referring cates the usual taper mounted thereon and top containing toFigure 3 of the drawing, 1 indi ed spindle, 2 a bobbin having a recess ain its an inverted cup-like member b 1 having an opening 0 thereinarranged eccentric to the axis of the sleeve or barrel bobbin-spindle. dis longitudinally split and is adapted to be fit over An attaching thespindle as shown 1933, Serial No. 685,451 1 (c1. 117 '2s) ing or recessg is sprung a balance arm h which encircles the barrel e'and may bemovable or fixed on said hub c.

The invention is not limited in its application tothe particular form of fiyer herein describdbut may be used on any formof fiyer. I v

The operation of the device is as follows:

In the spinning of thread, yarn etc, the material is takenfrom a bobbinor spool'that is fastened to a rapidly revolving spindle, and thematerials to be spun are passed through eyes of on the spindle to thetake-up bobbin the material is twisted upon itself in the directiondesired, either clock-wise or counterclock-wise. material to be twistedof varying diameters and the contributory tension by having on the flyerWhat Iclaim and desire to Patent is:-
